但绝大多部分实际问题都是分布不均衡的(如异常检测时,正样本只有100个、负样本10000个,如果采用Accuracy来评价模型性能的话,我们可以将所有样本判定成负样本,而此时会得到99%的Accuracy,但这种预测结果是不具有实际应用的),采用Accuracy无法有效衡量模型的性能。因此,便有了多种评价指标,如TP_rate、TN_rate、...
metrics=[{'name':'accuracy','function':accuracy_multilabel}] 因为是多标签分类,所以我们用的是准确率衡量指标是accuracy_multilabel。 我们把当前的参数设置,存入到日志记录器中。 代码语言:javascript 复制 logger.info(args) 开始构造模型了。 代码语言:javascript 复制 learner=BertLearner.from_pretrained_model...
More than 50,000 LRD label sensors are installed across the globe and testify to their accuracy and reliability.

1. The final label accuracy ranged from 92.9 to 99.4% in CFP and from 88.6 to 99.3% in the OCT. The noisier rate in the original dataset, the more improvement of label accuracy; however, the lower final label accuracy in general. The improvement is more in the initial iteration and ...
Accuracy rate placement of labels and ease of repeatability are always strong considerations. Return on investment is also crucial as well as the quality of the application. For example, no wrinkles, no crooked labels, no missing labels, no smudged or scuffed labels and always placed in the ...

However, if the test data is not balanced (that is, when most of the instances or records belong to one of the classes), or one is more interested in the performance on either one of the classes (biased), the accuracy metric will not be able to capture the effectiveness of a ...
